To me, “Brontosaurus” is a song that points at all manner of other musical futures while staying defiantly in the “pop” space – It’s surprisingly heavy for the Move, and between that crushing bass riff and Roy Wood’s whiny screamy vocals, suggests that perhaps the band was going to move into the psych-esque space of proto heavy rock that was forming around the time this was recorded. But, then again, there’s the (very Who-esque) switch up with the acoustic chords and piano at 2:32 where things start to swing and get a little Mod-y, and the freakout that follows suggests a possibility closer to the Small Faces (or even the Faces), that odd idea of a laddish band of musos who just wanted to mess around and have fun and somehow accidentally ended up producing some great music along the way. To see a band with as much potential for greatness in 1970 as the Move turn into ELO just a year later is kind of heartbreaking, in its way.
…Really. Just tragic.
